Belt Replacement

WARNING: This unit starts automatically. ALWAYS shut off
and unplug the compressor, and bleed all pressure from the
system before servicing the compressor, and when the
compressor is not in use. Do not use the unit with the shrouds
or belt guard removed. Serious injury could occur from contact
with moving parts. Hot surfaces. Risk of burn. Pump head, and
surrounding parts are very hot, do not touch (see the Hot
Surfaces identified in Fig. 2). Allow compressor to cool prior to
servicing.
1. Set the Auto/Off lever to "Off", unplug the unit, and relieve all
air pressure from the air tank.
2. Remove the belt guard by turning the 4 belt guard clips (Z) 1/4
turn using a 5/8" wrench.
3. Mark motor position on
saddle.
4. Loosen the motor
mounting screws and
slide the motor toward
the air compressor.

Adjusting Belt Tension

1. Slide motor into original position, line the motor up with the
mark made earlier on saddle.
2. Tighten two outside
motor mounting
screws enough to
hold the motor in
place for checking
pulley and flywheel
alignment.
3. The belt should deflect
1/2" (13 mm)at mid-
way between the pul-
ley and the flywheel
when a 5 pound
(2.26 kg.) weight is applied at the midway point.
3. When proper belt tension is achieved, tighten all four motor
mounting screws. Torque to 20-25 ft-lbs (27.1–33.9 Nm).
NOTE: Once the motor pulley has been moved from its factory set
location, the grooves of the flywheel and pulley must be aligned to
